SPRING-MOTOR.

SPECIFICATION formingpart of Letters Patent No. 229,113, dated June 22, 1880.

and to letters or figures of reference marked thereon, which form a part of this specification.

motors in which a coiled spring or connected succession of steel springs are wound up to their maximum-force power and held to that power until the uncoiling of the springs or spring requires further attendance. A train 'of multiplying-gear upon shafts journaled within a main frame ends with a pinion upon a shaft carrying a flywheel. The shafts upon which this multiplying-gear is hung are preferably three in number, and the ends of the shafts outside of the frame are provided with elbow-cranks, double cranks, or the like, and thus allowing the motor to be used for various purposes, as the crank upon either shaft is employed.

The lower shaft, having a minimum of speed, may be employed as a pumping device for house or church organs. The next, being of greater speed, may be used for other light purposes, as may be desired, and the maximum speed, derived from the upper shaft, may be applied to light lathes, scourers, burnishers, dentists engines, and the like by attaching the belt to the fly-wheel.

It will thus be seen that the object of the invention is to provide a portable spring-motor having connections giving dilferent rates of speed, and necessarily of power, adapted to be applied to various purposes, not all herein specified.

In the accompanying drawings, Figure l is a side elevation, partly in section; Fig. 2, an end elevation, and Fig. 3 a detail.

Referring to the drawings, A represents the frame, of any desired shape or size, in which My invention relates to that class of spring- (No model.)

is journaled the shaft 1) of the drum B, which contains the spring or motive power. This drum is provided with a gear, which meshes with a pinion, 0, upon a shaft, G, journaled in the main frame, as shown.

Upon the shaft 0, and rigid therewith, is a gear-wheel, D, which meshes with a pinion, E, upon a shaft, 6, rigid upon which is a gearwhee1,F, which meshes, in turn, with a pinion, Gr, upon the fly-wheel shaft g, which carries a fly-wheel, 00, having a pulley-connection, as.

The foregoing constitutes the train of multiplying-gear. p

The spring or springs are wound up by means of a hand-lever, as shown; but a treadle may. be employed, if desired. The lever M is pivoted at m, and carries pivoted pawls m m, which en gage alternately with a ratchet-wheel, M, upon the spring-shaft. A proper detent, y, prevents the spring from unwinding except by operating the machinery or train of gear.

Upon one endof the lower shaft, 0, is a crank, c, and upon the other end a double crank, (3. Upon either end of the shafteis a crank, 0. These connections may be of any sizeor form for convenient connection with any desired machinery or device.

Upon the shaft 9 is a rigid pulley, G, the recess in which allows lateral motion for a lever, I. Upon the pulley G is a pin, and a similar pin upon the lever I causes the looking of the pins with each other, and l the consequent stoppage of the mechanism when the shoe is forced in the proper direction by the lever 1 as is obvious. This lever I bears by its gravity upon the pulley at all times; but to give a tension device at this point I providea thumb-screw, I, which, bearin g upon the lever 1 allows the operator to adjust the tension or friction to suit.

In this brake and friction device consists the first part of my invention, and in the double-pawl winding device lies the second. 7

From the foregoing the operation of the machine or motor is obvious.

What I claim is- 1. The combination of the lever 1 thumbscrew I, and pulley G with the locking-pins and fly-wheel shaft of a spring-motor, .as and for the purposes specified.

2. In a spring-motor, the multiplying-gear In testimony whereof I affix my signature B, the journaled shafts a, e, and. g of which in presence of two witnesses. have cranks for giving different rates of speed,
